Chapter 15: recommended Discussion questions: 1

Due Monday, April 20. It is suggested that you make a copy of your solutions to keep.

I. Electronic spectroscopy

1. Atkins Problem 14.1

2. Atkins Problem 14.6 (short)

3. Atkins Problem 14.7

4. Atkins Problem 14.8 (short)

5. Atkins Problem 14.14. This problem applies symmetry to evaluate selection rules for electronic transitions. Part (a) requires no hint. For part (b), you might for example consider formaldehyde. Take the n orbital to be the p_y orbital on the oxygen, where the z axis is coincident with the C-O bond and the y axis lies in the plane of the molecule.

II. Introductory NMR

6. Atkins Exercises 15.1b, 15.2b, 15.6b, 15.7b, 15.8b
